I plan on buying a bump-start .21 and conversion and I wanted to know which .21 would be best for the Revo.I also need to know which BB conversion is the best to get.I have narrowed it down to the OS VSpec, RB S7 II or RB Worlds S7 II X3.One more thing.What drivetrain upgrades should I get to handle the power of the .21?


Thanks,
Mark

Check the Traxxas website, they now have a 3.3 which is probably like a .20. New Revo 3.3R too.

No Traxxas engine for me.That's why as soon as I get the Revo the 2.5 and exhaust header and pipe are going to EBay..
 
How good are you at tuning? If you are so-so, then stay away from the V-Spec, IMO. I hate tuning mine.

You should not have to worry about drivetrain breakage with the engine upgrade, in most circumstances. No upgrades needed just for the increase in power.
